mad as a wet hen
A wet hen is like a kid who just got grounded and then told they have to eat a whole pie for breakfast. They’re so mad, they’ll probably lay eggs in your pants.
My uncle was mad as a wet hen when he found out I stole his TV remote.
That chicken was so angry, it pecked my neighbor’s cat and laid an egg in the mailbox.
He got dunked in water three times and now he’s got a grudge against the entire farm.
